' 'with and with a mop, for removing excess drawing forming a part of this specifica' Aio of water from the mop.

More particularly stated, my inventionv comprehends a mop wringer of the general type just mentioned, in which .I provide an improved supporting bar, connected with the drain cu and u'sed for detachably connectin the drain cu with the pail.

' y invention urther contemplates an improved supporting bar, for adapting a particular drain cup, or a drain cup of given size, upon pails of different sizes. o

My invention also comprehends a number of minor improvements upon mop wringers of the general type here contemplated, for improving the efficiency thereof. n

Reference is made to the accompanying tion, and in which like reference characters indicate like parts throughout all of the iigures.

Figure 1 is a substantially central section through one form of my invention.

Figure 2 is a view of the mechanism shown in Figure 1, but partly in section and partly broken away; this view also indicating how the drain cup is sprung into position.

Figure 3 is 'a view paitl a plan and partly a section, of the mecanism shown in Figure 1.

Figure 4 is aperspective of the form of vsupporting bar shown in Figure Y Figure 5 is a fragmentary view, partly a plan and .partly a section, showing another forn'i of my invention.

Figure 6 isa fragmentary elevation of the supporting bar shown in Figure 5.

` Figure 7 is a section on the line 7 -7 of Figure', looking in the direction indicated by the arrows.

I will first describe the form` of my invention shown in Figures 1 to 4 inclusive.

A pail 8, made preferably of galvanized sheet steel, is provided with an annular bead 9 and with a bail 10 these parts be-v ing of the usual or any desired construction. v

A drain cup is shown at'11, and is made of sheet material, preferably galvanized I The drain 'cup is rovided with drain holes 12, having suita le form to facilitate to be wrung.

The drain cu 11 is provided with a rim 13 of annular orm as shown, this rim being smooth and rounded, and provided with an annular flange 14 extending outwardly.

A supporting bar is shown at 15 and is made of metal, preferabl steel. The supporting bar 15 is providedywith a portion 16 integral with it and of arcuate form, as illustrated particularly in Figure 4.

This arcuate portion-of the supporting bar is provided with two holes 17, 17; and two rivets 18, 18 extend through this hole and through similar holes in the rim 13 of the drain cup.

The supporting bar 15 is provided adjacent its ends with notches 19, 19 and 20, 20 and' the discharge of excess water from the mop thus, at each of its ends, practically fashioned into a double hook. The ends of the supporting bar are adapted to lodge against the ears 20, of the pail.

The purpose of the notches 19, 19 and 20, I 2O is to adapt the drain cup and supporting bar for use upon pails of different sizes.

In order t'o mount the drain cup. in a pail, the notches 19, 19 or'the notches 20, 20 as the case may be, ai'e slippedover the rim 9, the drain cup 11 extending down into the pail. Then the outermost' portion of the lange 14 is forced downwardly, as indicated by the Y arrow in Figure 2, and brought to rest upon. the bead 9, thus forcing the ends o f the supporting bar against the ears of the pail.

The supporting bar 15 has a certain amount of spring, and is caused to flex a little asthe rim 13 of the drain cup is forced into position. Thus the drain cup is supported by aid of a little spring pressure.

By giving the supporting-bar 15 a small amount of spring, another useful purpose is brought about. When the drain cup is pressed downwardly into position, so that the ends of the supporting bar are forced tightly against the ears 20a, 20?, there mist be a yieldingof either tlie pail or the sup orting-bar; and unless the sup orting bar h amount of spring, tide pail must do all of the yielding), and this tends to distort the pail. Hence giving the supporting bar 15 a slight amount of spring, the shape of the pail is maintained to better advantage.

As the supporting bar is pressed sidewise by the drain cup, it might have a tendency to ride upwardly and t us become displaced as a slight I los ' relatively to the rim 9, except for the form of tite hooks 19, 20. As the hooks extend slightly under the rim they prevent the supporting bar from becoming misplaced, and practically guide the 'ends of the bar into proper engagement with the ears of the pail.

Then the drain cup is forced downto 'the limit of its travel, the iange 14 of the drain cup lodges directly upon the top of the rim,

thus giving a iirm support to the drain cup.V

In Figures 6 and 7 I show another form of supporting bar, the same being adapted for use in the form of my invention appearing in Figure 5.' l

The main or body portion of this form of supportingbar is shown at 21, and detachably connected with it is an extension piece 22. The portion 21 is provided with a slot 23, and the extension piece 22 is provided with a slot 24.

A rivet 25 extends through the extension piece 22 and also through slot 23. This rivet- 27 and sliding the extension piece 22 relatively to the part 21, can vary the length of the supporting rod as a whole., By so doing, he can adapt the supporting rod for use with the drain cup 13, upon pails of other sizes than those for which the supporting bar shown in Figure 4 are adapted. i

The manner in which a mop wringer of this general kind is used is too well known. to need any detailed description. rIhe mop is forced into the drain cup and turned by hand, so as to cause excess of water to low through the drain holes and collect in the bottom of the pail.

As may be noted from the foregoing description either form of my in vention may be used for adapting a particular drain cup, or a drain cup of a particular size, to be used with pails of different sizes.

This increases the adaptability of the mop wringer, enabling it to be sold and used in avariety of relations in whichit could nototherwise be employed to advantage.

nism here shown and described, as variationsv may be made therein without departing from my invention, the scope of which is commensurate with my claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows 1.- A mop wringer, ncomprising a pail, a drain cup mounted within said pail, and a supporting bar connected with said drain cup and provided with recessed portions for detaehably engaging different portions of the rim of said pail, said supporting bar having a length between its recessedV portions slightly less than the diameter of the top of the pail with the drain cupv wedged in between said supporting bar and that portion 'of the rim within thesinaller'arc of the circle subtended by the supporting bar.

2. The combination of'a pail provided with cars and a drain cup, said drain cup having a supporting bar connected therewith, said supporting bar being long enough to reach from one of said ears to the other and adapted to rest `against the sidesof said ears which face the same direction, with the drain cup wedged in between said supporting bar and -supporting bar connected therewith, said sup porting bar being long enough to reach from one of said ears to the other and adapted to rest against the sides of said ears which face the same direction, said supporting bar being provided with hooks extending underneath the outer portions of said annular bead, the

'ears 0f said pail, serving as limiting" stops for said supporting bar with the drain cup wedged in between the supporting bar and that portion of the annular bead of the pail within the smaller arc of the circle subtended by the supporting bar, with the bar forced against the ears, and with the rim of said drain cup resting upon said annular'bead of the pail.
